Genes affected

ENTPD3 (HGNC:3365): (ectonucleoside triphosphate diphosphohydrolase 3) This gene encodes a plasma membrane-bound divalent cation-dependent E-type nucleotidase. The encoded protein is involved in the regulation of extracellular levels of ATP by hydrolysis of it and other nucleotides. Multiple transcript variants have been described.

The c.874C>T (p.R292W) alteration is located in exon 8 (coding exon 7) of the ENTPD3 gene. This alteration results from a C to T substitution at nucleotide position 874, causing the arginine (R) at amino acid position 292 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
